Answer:
A, B
Step-by-step explanation:
Plant cells and animal cells differ in multiple ways, even though we all have cells to survive.
There are two major differences between plan cells and animal cells; ones which can help differentiate, when looking through a microscope to determine whether plant or animal, which it could be, for example.
To begin with, chloroplasts are cells that enable the outside structure to perform photosynthesis. It's green in color, so you can envision it with plants being green and this cell being green. Animals don't need photosynthesis, therefore this is only available in plant cells.
Plant cells also have another distinguishable element called plant walls. These plant walls provide firm structure, much more than what plant and animal cells have called the cell membrane, which has a somewhat rectangular structure.
Both cells have cell membranes which keep their stuff together (think of it as a jello film keeping everything inside!) and both cells need mitochondria as well, making A and B the only logical explanation.
